how to write php code to a file with php

问题

For part of my website I need to be able to write php code to a file with php. For example:

$filename = "RtestR.php";
$ourFileName =$filename;
$ourFileHandle = fopen($ourFileName, 'w');



$written =  "
    <html>
    <body>
    <?php
    echo \"I like the color \".$_SESSION['color'].\"!!!!\";
    </body>
    </html>

";

fwrite($ourFileHandle,$written);

fclose($ourFileHandle);

But, instead of creating the file, it throws this error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING on line 14

What am I doing wrong and what is the right way to write php code to a file?
EDIT:
I think I might need to make myself clearer... I want the SESSION to be determined when the newly created file is loaded. Technically I don't want to get the session on this page, but instead on the page I am creating!!! I want to write the code to the file, not the output of the code!

Finally figured this out! I needed to escape my $ symbols! Like this:

$written =  "
<html>
<body>
<?php
echo \"I like the color \".\$_SESSION['color'].\"!!!!\";
</body>
</html>

";

Can't believe i didn't think of that ;)
Thank you all!

You can do like this :-

    <?php

    $filename = "RtestR.php";
    $ourFileName =$filename;
    $ourFileHandle = fopen($ourFileName, 'w');



    $written =  "<html>
                    <body>          
                        I like the color ".$_SESSION['color']."!!!! 
                    </body>
                </html> ";

    fwrite($ourFileHandle,$written);

    fclose($ourFileHandle);

?>

It seems relevant to mention php's HEREDOC in this context, e.g.:

<?php
$filename      = 'RtestR.php';
$ourFileName   = $filename;
$ourFileHandle = fopen($ourFileName, 'w');

$write =  <<<"FILE_CONTENTS"
<p>I like the color <?={$cleanSessionVars[ 'color' ]};?>.</p>

FILE_CONTENTS;

fwrite($ourFileHandle, $write);

fclose($ourFileHandle);

You're missing your closing PHP tag ?>.

Consider for a moment that what you are doing might not be the best approach anyway. The only use case I can think of for writing out PHP files with PHP would be for some compiled template code or weird caching.

Hello pattyd: Nice to see ya :) + Don't upvote/accept this answer:

I would suggest simplified in this way:

$written =  "
    <html>
        <body>
           I like the color \" $_SESSION['color'] \" !!!!
        </body>
    </html>
";

$fp = fopen("test.php", "w");
$string = '<html>
    <body>
    <?php
    echo "I like the color ".$_SESSION[\'color\']."!!!!";
    ?>
    </body>
    </html>';

fwrite($fp, $string);

fclose($fp);
